Patented Jan. 24, 1950 UNITED STATES PATENT OFFICE LAMP SHADE HOLDER Paul Chilo, Chicago, Ill.

Application February 13, 1947, Serial No. 728,333

4 claims. 01.' 24o-14s) This invention relates to lamp shade holders and more particularly it relates to the shade holding member upon which the lamp shade is attached, and it also relates to the means for connecting the lower ends of the armsjof the usual harp.

One of the objects of the present invention is to provide a shade holding member which shall be universally adjustable upon the harp. It sometimes happens that the harp is not, or cannot be attached to the lamp base so as to stand erect. As a result, with the ordinary shade holding members the shade is tilted somewhat, which of course is very objectionable. In accordance with my improved shade holder, the latter may be adjusted into upright position regardless of Iany slight inclination of the harp, so that the shade will be held in a level position.

Another object of this invention is to provide a more rigid, simple and ecient connecting means between the ends of the arms of the harp and to otherwise improve upon the connecting means.

With these and other objects and advantages in view, this invention consists in the several novel features hereinafter fully set forth and more particularly defined in the appended claims.

The invention is clearly illustrated in the drawing accompanying this specication, in which:

Fig. 1 is a side elevation upon a reduced scale of a lamp shade holder embodying a simple form of the present invention;

Fig. 2 is an edge view thereof;

Fig. 3 is an enlarged detail vertical longitudinal section through the shade holding member taken on the line 3-3 of Fig. 2;

Fig. 4 is a detail vertical cross section taken on the line 4-4 of Fig. 3;

Fig. 5 is an enlarged detail longitudinal section through a modified form of shade holding member;

Fig. 6 is a detail vertical cross section taken on the line 6-6 of Fig. 5;

Fig. 7 is a horizontal section taken along the line 'I-'I of Fig. 5;

Fig. 8 is an end view of the device looking in the direction of the arrow 8 in Fig. 1, and

Fig. 9 is an enlarged detail vertical cross section taken on the line 9-9 of Fig. 8.

Referring to said drawing, and first to Figs. 1 to 4 inclusive, the reference character IIJ designates the harp of the lamp shade holder which as is customary, is formed of a length of stout wire extend down from a short cross piece I2. In the form of shade holder seen in Figs. 1 to 4 inclusive, a metal cap I3 is provided in the shade holding member which has a centrally apertured top wall from which projects a skirt I4. Within the cap is a universal joint member, which as shown comprises a centrally apertured disc I5 which is formed with two oppositely disposed upturned apertured tongues I6 and with two oppositely disposed downturned apertured tongues II. Each pair of tongues is disposed at right angles to the other pair.

The c ross piece I2 extends through the aperture in each of the tongues II, and a pin I8 is secured in the skirt I4, and extends at right angles to the cross piece I2, through the interior of the cap and through the apertures of the tongues I'B.

Interposed between the cross piece I2 and pin I8 is a stout spring here shown as comprising a coiled compression spring I 9 which presses rmly against the cross piece and pin and creates suflicient friction between the cross piece and pin, and between the cross piece and lower edges of the perforations of the tongues in which it is held, and between the pin and the upper edges of the perforations of the tongues in which it is held.

Two diametrically opposite not-ches 28 may be formed in the lower edge portion oi the skirt directly above the cross piece. The cap covers the universal joint member therein, and the notches permit the cap to be swung upon the pin to adjust the cap relative to the cross piece without striking the same, except of lcourse in any abnormal adjustment of the cap.

The usual threaded shade holding stud 2| projects out through the aperture in the top wall of the cap and is provided with the usual nut (not shown) for securing the shade to the cap.

From the above it is apparent that the cap may be tilted upon the harp and may also be tilted on the pin if necessary to cause the cap to stand erect regardless of any slightly tilted position of the harp.

In the modiiied form of shade holder shown in Figs. 5 to 7 inclusive, the cap I3, pin I8 and stud 2| are of substanti-ally the same construction as -the corresponding parts of the preferred form.

However. in this form of the invention, instead of a centrally apertured disc and the rcoiled compression spring, the metal of the disc I5 is struck up with suitable dies to form two pairs of tongues 22, 23, one pair being struck downward to bear against the cross piece I2 of the harp, the other shaped to provide two bowed arms II, Il,which 55 pair being struck upward to bear against the pin I8. It is to be understood that the two pairs of tongues 22, 23 extend at right angles to each other. In this form of the invention, the disc l5' is preferably made of spring steel or other resilient metal, and that because of the inherent resiliency of the disc, the tongues exert enough friction on the cross piece and pin to hold the cap in any position of adjustment.

Referring now .to Figs. 1, 2 ,8 `and 9,rom the lower ends of the bowed portionsy Il `of the'harp, the arms are bent into parallel relation to each other and as seen at 26, and are bent inwardly.

at right angles to the parts 2B, as at 21.

The

extreme ends of the parts 21 are bent into op`I positely directed substantially semi-circular ex-4 tremities as at 28 which lie at right angles to the plane of the harp. The connecting piecebetween extending at right angles to the cross piece, a universal joint member having a pair of apertured tongues through which the cross piece extends and having another pair of apertured tongues disposed at right angles to the rst mentioned tongues through which the pin extends, and resilient friction means bearing against the cross piece and pin.

, 2. ,Ina lamp .shade holder, a harp having a Avcross piece and two arms projecting therefrom, a shade holding member having a, downwardly projecting skirt, a pin secured in said skirt and extending at right angles to the cross piece, a universal joint member having a pair of apertured tongues through which the cross piece extends and having another pair of apertured f 'tongues disposed atright angles to the first menthe ends of the arms Il of the harp, .as .shown,

comprises a ycircular stamping 24 having its mid die portion apertured and the metal around the aperture struck downward in the form of an annular flange 25 of an internal diameter Yto t snugly against the sides of the semi-circular'extremities 28 oi the harp arms.

From the periphery of the stamping '24 t0 the central aperture, the top wall of the stamping `may be crowned slightly, and the side wall 2 9 thereof formed with two diametrically opposite notches 30 through which the parts 21 enterthe annular space between the side `wall 29 and the flange 25.

The distance between the side wall 29 and flange 25 is substantially the same as the diameter yof the Wire from which the harp is made so that the curved extremities 28 thereof t snugly between the side wall and flange. l

.the curved extremities in the connecting means.

This arrangement provides avery rgid'connection between the harp ends and the connecting means, and in the manufactureand assembling of the parts, the connecting means is :caused 'to take a position :at right angles 'to the plane of -the harp. If desired, the edge of theiilange 25 may also be curled under the 'extremities of the harp to provide addedrigidity therein.

The lamp shade holder is attached to the usual threaded stem of the lamp 'base in the usual manner.

Having thus described my invention, it is 'obvious that various immaterial modifica-tions may'Vl be made in the same without Vdeparting from the tspirit of my invention; hence., I do not ywish .to be understood as limiting myself -to the exact form, construction, arrangement and combination of parts herein shown and described l.or uses mentioned.

What I claim as vvnew and desire to secure yby Letters Patent isz' l. In a lamp shade holder, a 4harp having a, v ,cross piece and 'two arms projecting therefrom,

.a shade holding memberhaving ra downwardly projecting skirt, a lpin securedin said skirt and tioned tongues through which the pin extends, and a coiled compression spring interposed between and bearing against the cross piece and pin. 3.
